Scientific paper

The data are a decomposition of the extinction curves published by Aiello S., Barsella B., Chlewicki G., Greenberg J.M., Patriarchi P., and Perinotto M. (1988A&AS...73..195A) in the parameter scheme of Fitzpatrick E.L. and Massa D. (1988ApJ...328..734F). Each extinction curve k(x) = (A(lambda)-A(V))/(A(B)-A(V)) is given by: k(x) = c1 + c2*x + c3* D(x,x0,y) + c4*F(x) Where x = 1/wavelength (in inverse micron), D is a Drude profile: D(x,x0,y) = x2/((x2-x02)2 + y2x2) and F is a polynomial of order 3: F(x) = 0.05392(x-5.9)2 + 0.0564(x-5.9)3 for 5.9* *.. | v * .. * * | *.. c2 1 | * 0 | * |^ * |Rv * |v|_ V B x0 5.9 8.0 x=1/wavelength (1/micron) Values of Rv, the ratio of total to selective extinction, can be found in Aiello et al. (1988A&AS...73..195A). (1 data file).
